OX NCBI_TaxID=509170; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=SDF; RX PubMed=18350144; DOI=10.1371/journal.pone.0001805; RA Vallenet D., Nordmann P., Barbe V., Poirel L., Mangenot S., Bataille E., RA Dossat C., Gas S., Kreimeyer A., Lenoble P., Oztas S., Poulain J., RA Segurens B., Robert C., Abergel C., Claverie J.-M., Raoult D., Medigue C., RA Weissenbach J., Cruveiller S.; RT "Comparative analysis of Acinetobacters: three genomes for three RT lifestyles."; RL PLoS ONE 3:E1805-E1805(2008). CC -!- FUNCTION: RNaseP catalyzes the removal of the 5'-leader sequence from CC pre-tRNA to produce the mature 5'-terminus. It can also cleave other CC RNA substrates such as 4.5S RNA. The protein component plays an CC auxiliary but essential role in vivo by binding to the 5'-leader CC sequence and broadening the substrate specificity of the ribozyme. CC {ECO:0000255|HAMAP-Rule:MF_00227}. CC -!- CATALYTIC ACTIVITY: CC Reaction=Endonucleolytic cleavage of RNA, removing 5'-extranucleotides CC from tRNA precursor.; EC=3.1.26.5; Evidence={ECO:0000255|HAMAP- CC Rule:MF_00227}; CC -!- SUBUNIT: Consists of a catalytic RNA component (M1 or rnpB) and a CC protein subunit. {ECO:0000255|HAMAP-Rule:MF_00227}. CC -!- SIMILARITY: Belongs to the RnpA family. {ECO:0000255|HAMAP- CC Rule:MF_00227}.
